SPECIFICATION forming part of Letters Patent No. 309,756, dated December 23, 1884. Apptication inegi october 29, 1884. (No modem lo @ZZ whom t may concern:

Beit known that I, GEORGE F. Bnl-3BE, of Hornellsville, in the county of Steuben and State of New York, have invented certain new 5 and useful Improvements in Pumps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, referio ence being had to the accompanying drawings, which form a part of this specification, andin which* Figure l is a vertical sectional view of a pump embodying my several improvements.

Fig. 2 is a horizontal transverse sectional view taken on the line :12min Fig. l. Fig. 3 is a detached sectional view, on a larger scale, of the bottom check-valve, its seat, and adjacent parts. Fig. et is a detail sectional view of the lower or main plunger. Fig. 5 is a side view of the latter, parts of the saine having been broken away for the purpose of showing the construction more clearly. Fig. 6 is a detail sectional view of the upper or supplemental plunger. Fig. 7 is a horizontal transverse sectional view taken on the line y y in Fig. l, and Fig. S is a vertical sectional view illustrating a modification in the construction of my improved pump.

The same letters refer to the same parts in all the figures.

This invention relates to pumps; and it has for its object to provide a device which shall possess superior advantages in point of sim- 5 5 plicity, durability, ease, .and certainty of operation, and general efficiency.

With these ends in view the-invention consists in the improved construction and arrangement of the constituent parts of the said pump, which will be hereinafter fully described, and particularly pointed out in the claims.

Referring to the drawings hereto annexed, A designates a tubular shell or casing, the lower endof which has a iiange, B, by which it is mounted upon the platform Cover the well, to which it may be bolted or otherwise secured. The upper end of the shell A has a iange, D, which supports a section, E, of tub- 5o ing, the lower edge of which has a flange, F,

bolted to the said shell. rlhe tube-section E is enlarged, so as to form a chamber, G, from which the spout H extends, as shown. TheV lower end of the section E is screw-threaded interiorly, and to it is secured a downwardlyextending tube section, I, which extends through the shell or casing A' and any desired distance below the same, and the lower end of which is provided with the valve-casing J, which is constructed with a dishing valve-seat, 6o K, which, by its peculiar construction serves to'prevent gravel, sand, and other impurities from settling upon the same and interfering with the operation of the valve. The latter, which is denoted by letter L, consists of an oval-shaped body, M, having a vertically-elongated core, N, of metal, around which is cast or formed a covering, O, of rubber, provided near its upper edge with an annular flange, P,of the same material, and of aboutthe sha-pe 7o. shown in the drawings hereto annexed.

The metallic core may be constructed with an annular ridge, forming the foundation of the rubber ange; but this is not indispensable. The lower en'd of the valve has a screw-thread- 75 ed recess, Q,in which is secured a downwardlyextending guide-rod, R, which, by extending into the well-tubing, prevents the valve from being reversed or otherwise misplaced, and which tends to hold it evenly to its seat; but 8o this guide-rod may be dispensed with when desired, inasmuch as the valve will usually be found to work satisfactorily without it.

This described construction of the valve is advantageous and desirable for several reasons, among the principal ones of which may be' mentioned that, first, it provides virtually a double valve, inasmuch as its lower and comparatively solid portion fitscompactly in the bore of the valve-seat, while the project- 9o ing annular soft-rubber iiange projects beyond said bore, and will fit tightly against the upper surface of the valve-seat. Again, in operation, the pressure of the water bearing down upon or against the valve-ange will cause the periphery or outer edge of the latter,

' which is of superior elasticity, to be first borne down against the seat, thus making a joint even before the valve proper reaches its seat.

' S is the well-tubing, which is screwed into roo and extends downwardly from the lower end of the valve-chamber.

rI he lower end of the pump tube or cylinder I is provided with a lining, T, of brass or other suitable material, of suiiicient length to form a bearing for the lower or main plunger, whether the latter be raised or lowered, as will be hereinafter described. The said plunger, which is designated by letter U, consists of a bottom plate, V, leather packing NV, rubber packing X, middle plate, Y, having upwardly-extending arms Z Z, and top piece or cap A', having lugs B', by which it is mounted upon the arms Z, the whole being connected by bolts C', so as to form a cage for the ballvalve D', the seat for which is formed bya eentral opening, E', in the plates V Y and in the packing-disks. The upper end ofthe cap A' has a screw-threaded recess, F', to receive the, plunger-rod G'. The valve D' is constructed of a spherical metallic core, II', having a covering, I', of soft rubber. By this construction the weight of the valve is increased, so as to overcome the objections existing against ballvalves constructed of rubber alone, while on the other hand a much better and closer iit is secured and at a much smaller expense than where ba-ll-valves constructed of metal alone are used. By using the double packing` of leather and rubber between the disks `V and Y the leather packing, which, when wet, is liable to slip the sides ofthe cylinder, is constantly forced against the same, thus insuring at all times the successful operation of the plunger.

Screwed into the upper end of the section E of the pump is a cylinder, J', of brassor other suitable material, in which works the upper or forcing plunger, K'. The latter consists of two disks, the upper one ol' which, L', is concave or dishcd upon its under side, so as to serve to spread the leather packing M' and rubber packing N', which is interposed between it and the lower disk, O', which alsov serves as a clamping-nut, and which, as well as the upper disk, is suitably connected to sections of the pistonrod. rlhe rubber packing in this plunger serves, as in the case of the main plunger, to keep the leather packing at all times in contact with the walls of the cylinder in which it works.

The upper end of the piston-rod is pivotally connected, in the usual manner, with the upper end of the operating lever or handle P', which is mounted pivotally in the cap Q' of the pump. The said cap is constructed with a vertical slot, It', at the sides of which are formed flanges S', provided with perforated lugs T', to receive the pivoting bolt or pin U' ofthe lever P', which may thus be adjusted vertically, so as to raise or lower the piston-rod with its attachments, as the case may require. The lower end of the cap Q is provided with a flange, V', to receive bolts, by means of which it is connected to the upper end of the section E of the pump, and the upper end of the said cap is provided with a screw-threaded opening, IV', through which the pump may be primed, and which is closed by'a suitable plug, X'. The lower end of the cap Q is cored to receive the cylinder J' and a sleeve, Y', covering the same. The said sleeve is provided with a iiange or rib, Z', fitting in the lower end of the slot R' in the cap Q', so as to close the same and protect the cylinder J'frominj ury from any cause. This construction is necessary and important, for the reason that it is necessary to connect the operating-lever with the plunger-rod before inserting or placing it in its bearings in the cap Q', which could not well be done if the lower end of the said cap were entirely closed hence the utility of the rib or flange Z',which lls the lower end of the slot R'.

Screwed into the side of the upper end of the cylinder of the pump is a cock or faucet,

`A, to the valve of which, B2, is riveted or otherwise attached an operating-rod, C2, extending upwardly, and having a bearing for its upper end in the flange F of the section E, above which it is provided with a wrench or handle, D2, by means ofwhich it may be conveniently operated. This valve may be operated, when desired, so as to let out the Water above the main plunger, thus preventing the pump from freezing in` cold weather. Other suitable means may, however, be used for letting the water out without departing from the spirit of my invention.

The operation of my improved pump will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. It constitutes, when constructed as above described, a combined or convertible force and lifting pump, it being convertible from a force into a lifting pump by simply lowering the fulcrum of the operating lever or handle, so as to cause the auxiliary plunger to work in the chamber G instead of in the cylinder J', while by thus lowering the piston -rod the lower or main p lunger is caused to work in the lower end of the cylinder T.

The advantages of the herein-described construction of the plungers and valves and their packing have been already set forth. It may be further pointed out that by providing the tube-section I with the brassl lining T, which forms the cylinder proper, a true and accurate cylinder is produced at a small expense, and the interior diameter of the section J being thus reduced, the 'piston-rod, with its main plunger, may, by simply detaching the section E, be readily removed, whenever necessary, for the purpose of repairing or cleaning the pump.

In Fig. S of the drawings I have shown a modification of my invention, which consists simply in dispensing with the cylinder J' and in substituting for the top piece or cap, Q', a cap, E2,which is considerably lower, and provided with covered lugs F, affording bearings IOO IIO

for the operating lever or handle, which in this case is not adjustable, this pump being designed as a lift-pump only. This construction is designed, principally, with a view of reducing expense in cases Where the pump is to be used only for general use as a lift-pump, while the pump in its combined form is more advantageous for private and farm use.

W'hen' the pump is used in its latter shape, I prefer to provide the operating lever or handle with a perforated lug, G2, outside its fulcrum for the attachment of Windmill or other power, when desired.

The spout ofthe pump is to be screw-th readed to receive a nipple or reducer for the attachment of hose, when desired.

Havingthus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. A pump-valve consisting of a core of metal elongated vertically, and a covering of rubber fitting closely to the vertical bore of the valve-seat, and provided=with a lateral annular flange at its top portion projecting some little distance over the upper surface of 25 the valve-seat and beyond the upper surface of the metalcore, substantially as and for the purpose set forth.

2. In a pump, the combination, with an intermediate section having an enlarged chamber and provided with an upward-extending cylinder, of a top piece or cap having a slot to receive the -operating lever or handle, and cored at its lower end so as to receive the said cylinder, and an interposed sleeve formed with a vertical rib or flange to fill the lower portion of the said slot, substantially as and for the purpose herein shown and specified.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two Witnesses.

GEORGE F. BEEBE.
